BESETTING MECHANISM.

'origini nppnunn mea umn 2i, isis, semi in. 191s. semi To all whom it may concern.'

Be it known that I, EDWARD. J. BRANDT, a citizen of the United States, residing at Watertown, in the county of Jefferson and State of Wisconsin, have invented certain new and useful Improvements in Resetting Mechanism, of which the following is a. specification, reference being had therein to t e accompanying drawing.

The invention relates to improvements in a resettin mechanism for registers, calculators or li e devices and is a divisional application of my condin application Serial No. 223,786, file Marc 21, 1918. v

' It is an ob'ect of the invention to provide a sim le an eiiicient means for resetting a plura ity of indicators to a zero or normal position. n

A further object of the invention is to provide a mechanism of this character coinprising friction members adapted to bear against indicators and keyed to the shaft upon which the indicators are loosely mounte so that upon a rotation of the shaft lthe indicators will be correspondingly moved by the friction members to a zero'or normal position where they are held 'by a suitable sto v lilore specifically the invention comprises a resilient washer having separated resilient arms adapted to impinge upon an indicator to turn the indicator upon a rotation of the shaft u n which the spring washers are mounte to reset the same to a zero position, it, of course, being understoodfthat there are a plurality of indicators and a spring washer [for each indicator so that as one indicator is positively stopped upon its reaching 'a zero position the arms of the ring washer ride over its face until all of t e indicators have been lined up in a zero osition. In the preferred embodiment of) the invention the spring washers are normally out of contact y with the indicators and move into driving relation therewith u n an endwise movement of the shaft, but i found desirable the arms of the spring washerscan at all times be in frictonal contact with the indicatorsso that an endwise movement 'of the shaft is not necessary in order to reset the indicators.

In the accompanyin vdrawings I have illustrated the prefev embodiment of the invention, .but man changes may be made in construction an arrangement of parts 223,786. Divided and this application tied my 8, No. 294,400.

without departing from the spirit of the invention.

In the drawings:

Fig. y1 is a longitudinal sectional view through the machine.y y

Fig. 2 is a front view with a portion of the casing broken away to show the interior structure.

Fig. 3 is an enlarged vertical section of the forward portion of the machine.

Fig. 4 is a transverse vertical section through the-casing to show the front of the operating mechanism.

Fig. 5 is a detail fragmentary sectional view through the upper rollers for the indieating bands or strips and immediately associate parts.

Fig. 6 is a fragmentary longitudinal vertical section of the carrying mechanism disposed between each pair of indicating bands or strips.

Referring now more particularly to the drawings wherein like reference characters indicate corresponding' artis, the letter A represents the bottom or ase of the machine upon which a cover or casing portion B, usually formed of metal is mounted and secured through the medium of the flanges C. The casing is provided with a shelf or ledge D, slotted as at E for the passage therethrough of a plurality of keys F the same vement arrangement.

Below the shelf or ledge are a series of pivoted plates G connected to, the operating rods H and ada ted to be shifted by enga ement with the ngers or cams I carried y the movable bars J, one'bar, of course, be'- ing connected with each key, and as each operating rod and its associated indicating mechanism operates in the same manner the description of one operating rod and its mechanism will suice forall. Each operating rod for kthe purpose of illustrating a means for operating the register mechanism is shown asl carrying at its forward end a pwl K held upwardly with reference to the ttom or base ofthemachine by a spring k. The l awl K is positioned and held in position y the spring Ic to en ge a rotatable ratchet L fixed to rotate. with the roller M, all of the rollers and ratchets of the entire mechanism being carried by a common shaft N extending transversely through the machine and mounted for rotation in the opposite side-walls ofthe casing B. The ratchet is prevented from reverse rotation by a dog O pivoted in any convenient manner, it being here observed that the rollers always rotate in the saine direction, to-wit, the direction indicated by the arrow in Figure l, whether in a calculating process, or during a resetting of the indicators.

Peripherally of the roller M, which may be termed a driving roller, projects a multitude of pins or teeth 0 adapted to engage complemental apertures p in the counting and indicating band P, said band or strip being of continuous or endless character and being vertically positioned within the machine to pass around a similar idler roller Q loose upon a transverse shaft g extending across the machine and supported at one end by one-of the side walls of the casing as at Q2 and at its other end upon an interior support g3 fixed to the casing in any convenient manner. The band P. and the other bands throughout the machine carry the numbers to be indicated from one to any total desired and within the capacity of the band, for example, 99, it being my intention to use a pair of bands in association with each key which could indicate a total of 9,999 which would obviously render the same universal in its use and serve all ordinary purposes although of course any number of associated bands of each unit could be added should the particular occasion therefor arise.

The interfitting toothed and apertured portions of the roller M and the indicating band P is for the purpose of positively driving the band ythrough its course of travel upon the operation of its"rod H to successively present the numbers on the face of the band opposite a sight opening B at the forward top of the casing B to be readily observed by the operator of the'pmachine for ascertaining his totals.

Any convenient means may be employed for preventing over-running of the ratchet L and its roller M, as well as the associated parts receiving motion from the ratchet. There is provided on the lower face of the pawl K a bevel stop R adapted to engage and ride upwardly on the lug r on the face of the machine, the relative positions of the stop and lug being such that they co'me into engagement at about the end of a full stroke of the pawl. to force the pawl upwardly into crowding relation to the ratchet, that is to occupy the space between the teeth of the ratchet thus preventing the ratchet from any possible over-throw after each successive rotation.

To carry over from the band P to the adjacent band of ,a pair or unit represented by the character P', I form on the band P l a pin r which when the band reaches its 99 indicating position will contact with the free end of the pivoted lever S carrying a horizontally disposed pawl S pivoted thereto and held upwardly by a spring s bridging the lower end of the lever and the pawl as shown in Figure 6. `The lower end of the lever S and its pawl S are normally held in outward inactive position by the spring s, but in effective or operating posi-4 tion the nose of the pawl engages a ratchet T iixed to rotate with the driving roller T having a toothed and apertured engagement with the band P similar to the engagement between the rolled M and its band P. When the band P engages in its movement the upper free end of the lever S the lower end is forced inwardly and the pawl S carried thereby engages the ratchet T, rotates its roller T and correspondingly rotates the band P to carry over into one which added to the zeroes simultaneously presented by the band P will afford a combined indication of one hundred. A dog t3 prevents reverse rotation of the secondary ratchet and its associated parts. VVhle I have shown and described a special form of carry over mechanism it will be distinctly understood that any suitable or well known construction for accomplishing this purpose can be used and the resent invention is not limited to` any specific indicator actuating mechanism or carry over device but the present construction is merely described for the purpose of illustrating a means for operating the indicatorsl and for carrying over from one indicator to the other.

The indicators are operated successively upon the manipulation of the keys, and when' the work of the machine has been completed and it is desired to restore the indieating bands P and P to a normal or zero position Iv utilize the following instrumentalities which constitute the subject. matter of this application, which is a division of ny co-pending application Serial No. 223,-

The band P isprovided with a pin p `corres1 onding g with the pin fr" on the band P which has been described as operating the carry overlever S, but when it is intended to reset the indicators, hooks U are thrown into an underlying position with reference to the pins to engage the latter and hold all the bands in alined zero positions. The hooks U are carried by a rod u secured in arms u sleeved as at u2 upon the shaft `g and held against longitudinal movement on said shaft. The shaft is normally held in extreme right position with its handle W in a corresponding position, see Figure 2, by a spring fw bearing against the inner end of the shaft q and supported by the portion JB. This spring also frictionally holds the shaft in a normal position against rotation when the idlers Q are revolved thereon.

When it is desired to thrust the hooks U below the pins l" and p* it is Simply necessary to engage the handle and force the shaft inwardly against the resistanceof the spring w which corres ondingly carries the arms u'. to the left an places the hooks U directly in the path of movement of the pins and constitute a stop therefor.- y

Mounted upon the shaft to the left 4of each indicator is a friction clutchY adapted to yield and bear against the adjacent faces of the idler rollers Q which are vdished for this purpose as at Y Figure 5. This engagement takes place when 4the shaft is moved against the tension of the spring rw and the frictional engagement between thel members Y and idler rollers Q tempo# rarily converts said rollers into driving wheels and the rotation of the shaft by its.. handle w in the direction of the arrow `will keyed to the shaftas indicatedl at y and stops y2 on the shaft serve to limit the endywise movement of the otherwise freely mounted rollers Q so as to permit the resilient members Y-to impinge upon 4the rollyers when the shaft isshiftedand the in'-v dicators are to be reset. l
